Claims

[Claims for Utility Model Registration] An intake passage 2 passes through the interior in the vertical direction XX, and at a lower position in the vertical direction XX of the intake passage,
A carburetor main body 1 equipped with a throttle valve 3 for controlling the opening area of the intake passage 2, a recess 9C provided on one side of the carburetor main body 1, and a cover 10 covering the recess 9C. A fuel regulator chamber 12 is formed by the diaphragm 11 between the concave portion 9C of the carburetor body 1 and one side 11A of the diaphragm 11, and the cover 1
0 recess 10A and the other side surface 11 of the diaphragm 11
An atmospheric chamber 13 is formed at B, and the fuel regulator chamber 12 has a main fuel supply passage M that opens to the ventilary part V of the intake passage 2, and a low-speed fuel supply passage M that opens to the intake passage 2 corresponding to the throttle valve 3. In a downdraft diaphragm carburetor in which a low-speed fuel supply passage N connected to the nozzle hole B is opened, the opening position of the low-speed fuel supply passage N to the fuel regulator chamber 12 is set at a position above approximately the center of the fuel regulator chamber 12 in the vertical direction. A downdraft type diaphragm vaporizer with an opening.
